I hope everyone is doing well.

I got a call from one of the users of our lab that when they try to
log in, they receive the message "GDM could not write your
authorization file . This could mean that you are out of disk space or
that your home directory could not be opened for writing . In any case
it is not possible to login. Contact system administrator."   This is
true for any user who tries to log in.

I was able to switch to a console and log and look around.  "df" shows
me that my entire LVM drive of 37 GB is full!  I am shocked because
the automated email that cron sends me on a daily basis showed, up
until last week, that over 50% was free.  Now it's all used.

Spent some time using fancy find/ls/du commands and I was able to free
up a couple of MB of space.  But something doesn't add up.  The sum
total of all the files isn't 37 GB.  I rebooted into single user, blew
away tmp, emptied caches and trash files -- nothing is making a dent.
/Var is taking up about 200 MB (I know that's a common culprit).

What else could it be?  Could the drives me reporting the wrong file,
or are there other areas I should look in to remove files?

Thank you.
